How To Make A Combox In A Datagridview Change Output In Textbox In Same Datagridview
Jan 29, 2010
I am using VS2008 and I have a form which has a datagridview. This is for an invoice where I already have the user select the customer from a details view and want to have the items in the datagridview change based on what the customer selected. Then when the item is selected I want to have the price change accordingly.
So far I have the customer selction as well as the item combobox(not limited to cust items yet) appear, but I cannot figure out how to get the join of the 2 items (cust+item as the price varies from cust to cust) to change the price. Question is, is it possible to do this in the same datagridview, or should i try to just break this down some other way?

I know that sounds strange but I came across this website today that uses this ability and I've been going nuts trying to figure out how they do it.
The website is [URL]
Also here is a screenshot of the options I am speaking of
There is a combolistbox that has a list of topics.
Depending on what topic you choose will determine what checklistbox option will appear in the check list box.
What are they doing there to create that option? I was thinking that maybe they created 20 checkedlistboxes and then if the selection of the combolistbox is "THIS" then they set the getfocus to that checkedlistbox but that didn't quite work for me.

I have a DGV I am working on, and I have many columns.
For example I have Columns colcase(Combobox), colreportTime(Time)
the combox shows 4 cases {A,B,C,D}
what I need to do is if the user select "C"
the the colreporttime will show the time of this change unless the old value is C

I have a DGV.It has some columns.The columns are in the correct order e.g. 1,2,3,4 at design time.When I start debugging and then come back to VS, the order of the columns have changed and I have to put them back in the correct order everytime.After some testing I have realised it only occurs if
1) I make a change on the form that holds the DGV
2)Leave the form open in VS while I play the application ie. debug.

How to programmatically change foreground color and make bold text in individual cell location on DataGridView control (Visual Basic)?
I use "dgMatrix.Rows(r).Cells(c).Value = x" to assign individual numeric values to individual cells in a DataGridView control. My question; is there a similar way to change foreground color and make bold the text in this cell, by specifying the individual row/column cell location?
For example; for cell (row 3, col 5) in the DataGridView make text in cell say red and bold or blue and bold so as to highlight and distinguish individual cell contents. As needed, I will also need to reset these properties (foreground back to automatic/black and font from bold back to regular); the reset could be done globally to the whole DataGridView as opposed to indiviaually by cell.

I am running a stored procedure and presenting the data back to users in a simple datagridview. I'm unable to figure out a way to filter my data through the SQL side, so I wanted to see if I could filter data through the datagridview. Basically my sql query returns back values of "activity" that are either added or deleted, and I only want to present data back to users that are "added.' Is there a way to do this by filtering the contents of the datagridview?This is what I have in my codebehind for the page for both the SQL connection string, and the stored procedure. I'm assuming that this would be where I would filter the information.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles oncallsubmitButton.Click

Dim da As New SqlDataAdapter
Dim cmd As New SqlCommand

For a class project I'm supposed to write a program that requests a team as input and displays the players from that team in the first column. The players should be sorted alphabetically by their last name, and if they have the same name they should be sorted by first name accordingly. My program compiles and I'm fairly certain that I've done most of it correctly. The second column should be filled with the batting average of the corresponding player from the left column.
My problems are as follows:
1) I can't get the DGV output to show correctly, it posts the player's name with the batting average of that player in the following downward cell.
2) I'm not sure how to further use the .Split method to separate the first and last name after already separating the name from team/at bats/hits, and can't find any info regarding this topic. Also, I can't figure out how to sort in reverse, I've only seen the Ascending and Descending options so far for sorting.
3) Is the way I've figured the batting average the most efficient/correct way, or is there another better way?

Is there a way to make a DataGridView's column a combo ONLY in the "new row", and a read only textbox in all other rows? I want the user to be able to make a selection from the combo box, and when the row is finished and the "new row" moves down one, I want the column to become a textbox containing the what the user selected. My grid will be bound to a table witch contains a "category" column, that is drawn from a seccond table that i want the combo box bound to.

I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown
Dim ht As DataGridView.HitTestInfo = Me.dgvCalculatedResults.HitTest(e.X, e.Y)

I am having trouble getting the Student Name entered in the Student Name Form to change the Text titles of the GroupBox's on the Main Form and Schedule Form. I understand the logic of what needs to be done to some extent, but I am having trouble coming up with the correct coding.
Below is a snippet of the Student Name Form code that I tried most recently just to see if I could get any change to happen to the other 2 Forms when the Accept Name button was clicked. As of yet, I cannot get a change to happen at all in the groupboxes of the other Forms.[code...]

I have appended a column of checkboxes to a DataGridView using the following:
Dim chk As New DataGridViewCheckBoxColumn
DataGridView1.Columns.Insert(0, chk)
How do I change the checked state of a particular checkbox?
I have tried using the following code:
Dim val2 As DataGridViewCheckBoxCell = DataGridView1.Item(243, i)
val2.Value = True
DataGridView1.Item(243, i) = val2
The last line resulted in runtime error "InvalidOperationException was Unhandled
Cell provided already belong to a grid". Index 243 exists.

I'm selecting value from my database, passing it to datatable then giving DataGridView.DataSource value of datatable.The thing is that in those rows i'm also selecting some dates and problem is that my default date in database is '1900-01-01 00:00:00' because i use "smalldatetime". And what i want is this...when I find default value in database i want to show it like an empty string, like i said...because date is in smalldatetime format i can't do this in SQL query so i wonder how can I change this in DataTable or even better in DataGridView...of course, in code?
